Prove the Earth is round

Kumar said:
Shouldn't it be simple for you? Do you agree the question is extremely simple to answer? Didn't you say so yourself?

It it is not so simple & common as I mentioned' then I doubt everything. Similarily, Homeopathy working may also not be so simple to prove in science.

Can we get an answer from you to my question any time soon?

No you can't get more then that which I already mentioned, because niether I know more than that nor I will justify any more if we do not justify other systems.

OK, Kumar, is this a refusal to answer our questions of you about your own formula about how to calculate the "slope of a tennis ball"? Does this mean you cannot do even this simple mathematical task? Even by just showing your formula and workings again?

And, by implication, does it mean you agree you are actually unable or refuse to calculate the "slope" of any sphere at all?

If you will not show us any work on your part, just which formulae and calculations will you show us to support anything you are saying?
 
Still ducking and weaving, Kumar?

Have you no good answers for the big, bad skeptics' really simple questions?

Zep, it was just a tangential remark, you know.
 
Hello Zep & others,

I like the following words under Zep signature.

Like: Homeopathy, alternative systems, earth's shape etc.:D

Except that more and more papers by homoeopaths are now concluding that homoeopathy only "works" if the participants believe in it.

This makes it MAGIC. OK, you believe in magic, Kumar. Fine. But don't expect research scientists to take you seriously.

You do know that you have still not answered our questions here, Kumar? You are aware that we will not let them fade away just because you try to duck and weave and avoid answering them? And you do know what that makes you if you DON'T answer them?

Keeping to the subject of this thread, which is a thread at YOUR request, Kumar, I repeat: Are you refusing to answer our questions of you about your own formula about how to calculate the "slope of a tennis ball", a very small and very real sphere? Does this mean you cannot do even this simple mathematical task? Even by just showing your formula and workings again?

And, by implication, does it mean you agree you are actually unable or refuse to calculate the "slope" of any sphere at all? Such a simple and BASIC requirement to answer the question of this thread?

If you will not show us any work on your part, just which formulae and calculations will you show us to support anything you are saying?

Homeopathy is not magic, although real magic is bigger then any other thing.

Zep,

I repeat as per my previous postings.

Zep & others,

Please take it as 636.6 metres not 6366 metres. Just think, because I am unable to think at present by finding this calculation. It seems my calculator is giving wrong calculations. I taken formula as: E.Radius divided by 1/4th of E.circumfrance i.e 6378.1/10018.15 = 0.6366 Kms. It may mean If we tavel 1 km on round earth surface we will go deep by 0.6366 Km OR 636.6 metres. We can also take it as: to cover 6378.1 depth(slope i.e. maximum depth eqv. to radius) we have to travel a distance of 10018.15 Kms on round plain earth surface or at Sea surface.

I could not understand how it is coming like that. Pls do clarify. :(

I think this is Kumar's workings out. To travel "vertically" one earth radius you would have to travel 1/4 of the way around the world circumfrentially (or r*pi/2). This gives Kumar an "average" slope of 637 meters "vertically" down for every kilometer "horizontally" along the surface.

For some reason Kumar thinks that this should be linear.

Which I guess is where he ends up with the world being a cube. I tried without visual aids to demonstrate this but failed (even to my own miserable standards of satisfaction). I fear that Kumar will never get his head around it.

This is one of those occasions where a face to face explanation with much arm waving could work.

I am also about 99.99999999% sure Kumar is just yanking our collective chain

Don,

Thanks. Face to face or physical explanation is a better/real proof alike looking earth face to face or physically instead through cameras,computers,calculations,formulas etc.
 
So what Kumar has (quite probably correctly) concluded is that there is no test that a person could conduct, by themselves, with simple equipment to demonstrate that the earth is spherical (or near enough to).

- All experiments involving watching ships could be invalidated if some crazy idea of refraction in the atmosphere.

- Any test requiring measuring the gravitiational force at any place would requi far too sensitive

- Any experiment involving getting in a plane and flying somewhere involves a plane, and anyway you could be flying across a disc illuminated by a partially shielded sun

So for someone who never leaves their own immediate locale, the earth could be considered functionally flat.

For anyone*really* saying that the earth is either flat or cubic, where are the edges ?

Don,

Ok just tell how a ship can be partly invisible if it travels along with lattitude lines i.e elevated horizontal , from east to west.

Any experiment involving getting in a plane and flying somewhere involves a plane, and anyway you could be flying across a disc illuminated by a partially shielded sun

Pls refer the experiments as mentioned by me. Btw, when we see throgh a window of plane at some 4-7 kms height, why we don't see the earth as convex. If we can see the ship's bottom shinking, we should also be able to see earth as convex shaped from the plane.

So for someone who never leaves their own immediate locale, the earth could be considered functionally flat.

May be. I am bit fearful of falling as on a ball, since when earth is declared as round.:D

For anyone*really* saying that the earth is either flat or cubic, where are the edges ?

I don't know exactly but may be Antartica, Alaska...so on.
 
Kumar,

Sorry, didn't understand your first question but I'll try to answer it anyway.

For spherical-earthers, it doesn't matter whether the ship is travelling north-south or travelling east-west the hull of the ship would eventually be rendered invisible by the curvature of the earth on the grounds that a sphere is perfectly symmetrical.

For flat or cube-earthers, the hull of the ship would be rendered invisible by the same mechanism at work in mirages

http://science.howstuffworks.com/mirage.htm

So a flat or cube-earther could conceivably try to explain away disappearing hulls

Second point:

I won't refer to your experiments on the grounds that I cannot remember what they are. However:

- You can see the earth's curvature through an aeroplane window as long as you fly high enough
- The experiment to which I was referring is "what time GMT does it get light in...." indicates that the sun moves around some kind of three dimensional shape

Please provide evidence of edges
 
Mr.Don,

Thanks for explaining in details. I appreciate your work.

For spherical-earthers, it doesn't matter whether the ship is travelling north-south or travelling east-west the hull of the ship would eventually be rendered invisible by the curvature of the earth on the grounds that a sphere is perfectly symmetrical.

But this does not matches with the given dimentions & calculated average slopes of the earth.

For flat or cube-earthers, the hull of the ship would be rendered invisible by the same mechanism at work in mirages
So a flat or cube-earther could conceivably try to explain away disappearing hulls

What does it mean?

You can see the earth's curvature through an aeroplane window as long as you fly high enough

No it is not visible even from the 20-25000 feet height.

The experiment to which I was referring is "what time GMT does it get light in...." indicates that the sun moves around some kind of three dimensional shape
Please provide evidence of edges

I have already given my comments.

I am sorry Mr.Don, but I don't want to discourage furthur as all the awnser given to me are observational & calculations based which can never be physicals. The same is the case of homeopathy's existance. So I now conclude:

'Earth is round' or' homeopathy works' are both obsevational based by few & many respectively. We have to either accept the both or reject the both in this sense.

Thanks all for the contributions in never ending discussions as biased.
:)

With one tiny difference. In your nomencalture.....

Earth not flat and homeopathy a load of rubbish are both experimental based on many & many respectively. We have to either accept the both or reject the both in this sense.
 
Okay, one last try.. :)
Why is the duration of a day (sunlight) dependent on your location on earth? Easy one for the spherer's but quite hard for the flater's. I am not talking about seasons.

The concept of latitude gives you immediately at least a cylindical earth. This should not be to difficult to understand. I tried it yesterday with my ten year old niece. She got it. :D

Must not feed troll... must not feed troll... aarrgh! I can't resist!

(1) The only reason the "slope" calculations don't work for you is that you are deliberately ignoring the fact that the "slope" is a function of your position relative to the point at which you want to measure the "slope". You want to assume that there is a single value for the "slope", which is equivalent to assuming the earth is flat! No wonder your sums don't work.

(2) Yes, you can see the earth's curve from an aeroplane. Matter of fact, if you look carefully and compare with a straight-edge, you can see the earth's curve from a small (20 metre) cliff by the seaside.

Kumar,

Do you understand what is being told to you by these people above? Do you accept ANY of what they are telling you? If not, why not?

Do you still want to use this below as your calculation of the slope of any sphere? Or perhaps just for the Earth?

Can you look at these images and tell me if you think the horizon is curved or not? If not, why not?

Your friend Kumar is correct. You can't prove the Earth is round to an idiot.
